多层螺旋CT多维重建在泌尿系统疾病诊断中的应用

Multi-dimensional reconstruction of multislice helical CT in the diagnosis of urinary tract diseases

目的:探讨多层螺旋CT多维重建技术在泌尿系统疾病诊断中的应用价值。方法:采用16排螺旋CT薄层扫描并利用多维重建技术对50例泌尿系统疾病患者进行检查。泌尿系结石40例,肾癌2例,肾盂癌1例,膀胱癌2例,肾盂、输尿管交界处狭窄1例,肾损伤4例。结果:50例患者均获明确诊断。泌尿系结石CT多维重建可显示高密度结石致密影及结石形态、大小,与手术切开取石或体外碎石排石结果一致。5例肿瘤CT多维重建或MPR检查显示不规则软组织块影,并能显示管壁增厚,狭窄或团块样改变。膀胱肿瘤尚能立体显示腔内侵袭深度及与周围组织关系,与术中所见和术后病理结果相符。1例肾盂输尿管交界处狭窄能清晰显示狭窄部位、程度,肾盂积水情况。4例肾损伤患者可显示肾损伤程度、血肿范围以及周围脏器损伤情况。结论:多层螺旋CT多维成像分辨率高、检查时间短、侵袭性小、可增加图像立体感,使病变显示更为清晰,可作为泌尿系统疾病最有价值的诊断方法之一。

Objective：To evaluate the diagnoctic value of multi-dimensional reconstruction of thin slice helical CT in urological disease.Methods：50 cases（35 males and 15 females, average age 51 from 20-81） suffered with urological diseases under went multi-dimensional reconstruetions of thin slice helical CT. All eases were diagnosed including urinary stones 40, kidney cancer in 3, pelvis renabs cancer in 1, bladder cancer in 2, narrowing between pelvis renalis and ureter in 1, kidney injure in 4.Results：50 cases were deftnitely diagnosed. 5 cases was indicated unregular soft tissue by multi-dimensional reconstruction of thin slice helical CT even indicated the thickness, narrow or mass of blood vessel and relation of aound tissues. The helical CT results were same with the operative, pathological and ESWL results. Conclusion：Multi-dimensional reconstruction have the advantages of high resolution, rapid imaging and low invasivehess. The procedure can increase pellucidity and solid sense of images. It might be one of the valuable measures with helping the diagnosis of urological disease.
